Wireshark · Wireshark-dev: Re: [Wireshark-dev] How to find start of header in buffer (if not starting at 0th byte)

[Natalie Shapira <nd1234@xxxxxxxxx>]

Hi Hardik,

I use it that way:

descriptor_tvb = tvb_new_subset(nmi_tvb, 4, -1, -1);   // descriptor_tvb is a pointer to the tvb in offset of 4 bytes from the beginning

desc_tvb_remain_length = tvb_length(descriptor_tvb);

Hello,

In normal case packet header start at 0th byte of buffer, but in case of packet reassembled my packet header start after some offset.

In  above case my packet header start at 7th byte of buffer .

so i need to know what is length of individual buffer in my dissector program.

so can any buddy guide how to do this??

Regards,
Hardik Patel
